Hello,


After Authentication I store the userID in a datasnap session and in the

the Session userID.


So after the user is Authenticated by the login page the loginpage
shows the next page via javascript like : 


var s = serverMethods().GetSessionUserID();
(function that looks to the TDSSession)
window.location="http://server.com/newpage?Userid="+s.result;


This will open the newpage and in the Pageproducer onHTMLTag
I ask for the Userid via the Request.ContentFields and create the 
page for the user using the Userid.


But now if the user just type in the browser:


http://server.com/newpage?Userid=5
I don't see where I can check if the user is allowed to
view the Userid=5 page because in the  onHTMLTag event of the newpage
you can *not* ask for the TDSSession session Userid (always nil)


so, in the newpage I can check via javascript if the user is already
authenticated but I like to check also if the user is allowed to
view pages asked by the Request.ContentFields.


How should I do this?
